I skipped the OA and was directly contacted for a coding interview. It was quite dry. They didn't ask any behavioral questions and jumped straight into coding. The coding question itself was super easy - a simple stack problem of keeping track of parantheses. The extension asked to make a visual editor (so it was a bit more OOP) and simply remember the positions of the parantheses from the previous subtask and do some string manipulations depending on if you encountered a paranthesis there.

Collaborative problem solving, not like leetcode style. For of system designing and low level programming: visual machine, compilers. There is no special needs to prepare, just be familiar with the language chosen and think aloud.

Skipped past the OA, straight to first interview after resume screen. Then it was a 45 minute live coding round. More design style question than traditional leetcode. Did not make it past the first round.
